I'm not a Jorge fan but he had one video where he shows an outdoor plant that someone pulled up roots and all, and toss aside. It landed on a bare patch of ground and somehow managed to put down roots and survive! Laying in the sun! These plants can take quite a beating, without a doubt. Your issue, because you caught it in time, has hardly phased your plants. I have a plant in scrog right now, I broke a main branch of, right at the junction with the main stem. It was hanging but a thread. I merely propped it up enough to make contact with the main stem. she re-attached within 3 days! Canna never ceases to amaze me!
